摘      要：Poly(phenylene vinylene) (PPV) him was synthesized via a soluble precursor polymer. Strong fluorescence at 500-600 nm was observed in both precursor and PPV him. Room-temperature conductivity of PPV him doped with FeCl3 depends on the elimination temperature, the concentration of FeCl3 and doping time. The maximum conductivity of doped PPV at room-temperature can reach about 40 S . cm(-1). The temperature dependence of conductivity was controlled by 1D-VRH (1 Dimension Variable Range Hopping) model with T-0 value of 3.9 x 10(3) K. Non-Ohmic conductivity resulting from Schottky effect was observed and the value of converted voltage from Ohmic region into non-Ohmic region at the current-voltage characteristic was found to be dependent upon the work function of electrodes.
